ISD33240 Chipcorder

Hello all,
I am trying to interface a BS2 with an ISD33240 ChipCorder which is the 240 second version of the 33000 series. I have downloaded all the application notes, product briefs and datasheets and I am still having difficulty understanding how to communicate via the SPI (serial peripheral interface). The chip has four microcontroller interface pins named: SS, SCLK, MOSI, and MISO.
SS slave select pin (or chip select)
SCLK serial clock pin
MOSI master out slave in
MISO master in slave out
The data sheets give timing diagrams for these pins but does not specify if the serial-in is LSB first or MSB first. My question is does the BasicStamp2 support SPI and if so how do I clock data into the device while simultaneously clocking data out of the device (basically as one bit is shifted in on MOSI, one bit is shifted out on MISO).
Any help would be greatly appreciated,
Ricky
